Abstract

The invention relates to a waste water treatment device, specifically a waste water photocatalytic treatment device, comprising a treatment room, the two ends of the treatment room are water inlet and water outlet respectively, and the bottom of the treatment room has a drain; the treatment room is equipped with a plurality of ultraviolet lamps and A photocatalyst plate, the photocatalyst plate is corrugated, and the ultraviolet lamp and the photocatalyst plate are installed at intervals; one end of the photocatalyst plate and the ultraviolet lamp is fixedly installed on a fixed frame, and the fixed frame is installed in the treatment chamber and The junction of the water outlet chamber; the other end of the photocatalyst plate and the ultraviolet lamp point to the water inlet. In the wastewater photocatalytic treatment device provided by the invention, the oxidant solution and sewage can be fully mixed into the treatment chamber; the contact surface between the photocatalyst plate and water is increased, the water flow is buffered, and the catalysis time is increased. The reaction efficiency and sewage treatment effect are improved.

Description

technical field [0001] The invention relates to a wastewater treatment device, in particular to a wastewater photocatalytic treatment device. Background technique [0002] The photocatalytic oxidation method has been widely recognized for its outstanding advantages of low cost and no secondary pollution. Organic pollutants such as dyes, surfactants, organic halides, pesticides, oils, and cyanides in sewage can be effectively converted into TiO through photocatalytic oxidation. 2 Surface degradation, decolorization, detoxification, and finally complete mineralization to CO 2 、H 2 O and other inorganic small molecular substances, thereby eliminating pollution to the environment. [0003] The use of nanotechnology is an important way to improve the photocatalytic efficiency of titanium dioxide. This is because nano-titanium dioxide has a huge specific surface area, and the ability of its surface to adsorb organic pollutants is greatly increased; at the same time, due to the...
